30th'. At length I can say that the cough has ceased. It is seldom that so much trouble would have been taken with a dog. It is the neglect of the medical attendance which is often the cause of death. Professor Delafond, of Alfort, gives a most interesting and complete table of the usual diagnostic symptoms of pleurisy and pneumonia. PLEURISY. 'Commencement of the Inflammation'. Shivering, usually accompanied by slight colicky pains, and followed by general or partial sweating. Inspiration always short, unequal, and interrupted; expiration full; air expired of the natural temperature. Cough unfrequent, faint, short, and without expectoration. Artery full. Pulse quick, small, and wiry. 'Auscultation'. A respiratory murmur, feeble, or accompanied by a slight rubbing through the whole extent of the chest, or in some parts only. 'Percussion'. Slight, dead, grating sound. Distinct resonance through the whole of the chest, and pain expressed when the sides are tapped or compressed. 'Terminations' Delitescence. Cessation of pain; moderate temperature of the skin; sometimes profuse general perspiration. Respiration less accelerated; inspiration easier and deeper. Pulse fuller and softer. Breath of the natural temperature. Return of the natural respiratory murmur and resonance. The walls of the chest cease to exhibit increased sensibility. 'Effusion, false Membranes'. Inspiration more and more full. 'Auscultation and Percussion. Complete absence of the respiratory murmur, with the crepitating wheezing always at the bottom of the chest; sometimes a gurgling noise. Vesicular respiration very strong in the upper region of the chest, or in the sac opposite to the effusion. 'Continuance of the Effusion'. Absence of the respiratory murmur gains the middle region of the chest, following the level of the fluid. These symptoms may be found on only one side; a circumstance of frequent occurrence in the dog, but rare in other animals. The respiratory murmur increases in the superior region of the chest, or on the side opposite to the effusion. Inspiration becomes more and more prolonged. Breath always cold. Cough not existing, or rarely, and always suppressed and interrupted. Exercise producing much difficulty of respiration. 'Resolution or Re-absorption of the effused fluid, and Organization of false Membrane, the consequence of Pleurisy'. Slow but progressive reappearance of the respiratory murmur, and disappearance of the sounds produced by the fluid. Diminution of the force of the respiratory murmur in the superior part of the chest, or of the lung opposite to the sac in which the effusion exists. Gradual return of the respiratory murmur to the inferior part of the chest. Inspiration less deep, and returning to its natural state.
